Desktop machines using alternating current, most people may not be the computer laptop battery attached great importance to energy-saving features, but need to use battery-powered notebook computers, the use of energy-saving features should be taken seriously. How to design computer hardware more energy-efficient, this is not a user problem to be solved. The user can do is set up on the computer the effective use of energy-saving option.

Energy-saving settings require the user to adjust two: First, the computer's BIOS setup program on the energy-saving mode in the settings; most important thing is the operating system such as Windows 98, there are many energy-saving settings and operations. In the practical implementation of computer systems, Windows systems should take precedence over energy-saving settings in the IBM ThinkPad A21M Battery CMOS settings.

1. BIOS in the energy-saving settings

In the CMOS settings, most had a "Power Savings", which can choose to "Maximum Battery Life" and "Maximum Performance" and other options. "Maximum Battery Life" is the default power saving mode setting. Notebook computer power saving mode in several states, such as the Idle Mode Idle Mode, Standby Mode standby (wait) mode, Suspend Mode suspension (sleep) mode. Notebook computers, these settings have been able to regulate power consumption, mainly in the computer into energy-saving state, the timely closure of some without the use of the system equipment. If the wait state, turn off the screen and hard drive; into hibernation, apart from a close monitor and hard drive, but also the contents of memory can be saved to the hard disk, the basic maintenance of the entire computer system shut down, once activated, or restart the computer, desktop will be accurately restored to pre-hibernation state. The energy-saving settings in the IBM ThinkPad A20M Battery CMOS, mainly set by the Idle Mode to enter Standby Mode to Standby Timeout time, set to enter Suspend Mode from Standby Mode to Suspend Timeout time. Phoenix BIOS notebooks are most common. Different energy-saving BIOS settings may be somewhat different, it should carefully read the screen prompts.

2. Windows in the energy-saving settings

For the average user, in the Windows system to operate a better understanding of energy management can be simpler. Windows Help file, in the "management of hardware and software" entries, there are two notebook computers with energy-saving elements relating to: "Managing energy consumption" and "use of portable machine" in the "management laptop on the power." Energy-saving settings during Windows, should read the contents.

In the Windows "Control Panel", click "power management", you can open the "Power Management Properties" dialog box. Shown in Figure 1, in the "Power Management IBM ThinkPad A20 Battery Properties" dialog box, should be "power scheme" is set to "Portable / Laptop" and reasonable arrangement "system waiting for", "close the monitors" and "A Turn off hard disks "and other options. Different computer can control the option to have some differences, the new factory and the latest computer software will be more workable options, detailed settings should be based on the computer's own features and Windows Help files to carry out.

If you need to completely run out of battery in the electrical energy discharge means no need to look for something else, just in the "Power Management Properties" dialog box "power scheme" is set to "always open" and will "system waiting for" and "Close Monitors "and other IBM 02K7054 Battery options set to" never ", and also allow computer to automatically run a number of computational complexity of the 3D demo program, which will soon be able to use dry battery power remaining, of course, do not forget these disposal to unplug the AC plug.

Q: My laptop heat too powerful, how to run?

A: small notebook computers because of space caused by poor cooling effect. If your notebook with the crash with the use of, and the board felt that their hands thoroughly hot, then mostly because of heat caused by bad, you is not the laptop resting on the bed to use it? Notebook computer batteries because of the need to use, it is designed to attach great importance to the management of the power, if the instructions on the notebook power management in more understanding and careful implementation, we can make a more rational and efficient power consumption, so that it makes the notebook IBM 02K6928 Battery power less in the form of heat distribution away.

Q: laptop computer using AC power, the machine need a removable battery?

A: When using the AC, the machine's battery power while not in the state, but will still be charged. It would be advisable to remove the battery, this battery will be more durable.

Q: Can long-term use laptop AC?

A: Of course you can, and I'm sure some notebook "lifetime" IBM ThinkPad R32 Battery is only used alternating current.
